You are the network administrator for your company. The network consists of a single Active Directory domain. The network contains two IP subnets connected by a Windows Server 2003 computer running Routing and Remote Access. All servers run Windows Server 2003. All client computers run Windows XP Professional. Each subnet contains a domain controller. Each subnet contains a DHCP server, which provides TCP/IP configuration information to the computers on only its subnet. The relevant portion of the network is shown in the exhibit.
You recently implemented a Microsoft Internet Security and Acceleration (ISA) Server 2000 array on the network to provide Internet connectivity. The ISA Server array uses Network Load Balancing on the internal adapters. The array’s Network Load Balancing cluster address is 172.30.32.1.
You configure the DHCP server on Subnet1 to provide the array’s Network Load Balancing cluster address as the new default gateway. You configure the DHCP server on Subnet2 to provide the IP address 172.30.64.1 as the default gateway for Subnet2. Users on Subnet2 report that they cannot connect to Internet-based resources. They can successfully connect to resources located on Subnet1.
Users on Subnet1 can successfully connect to Internet- based resources. You investigate and discover that no Internet requests from computers on Subnet2 are being received by the ISA Server array. You need to provide Internet connectivity to users on Subnet2.
What should you do?
Exhibit:
A.
Configure the DHCP server on Subnet2 to provide the address 172.30.32.2 as the default gateway.
B.
Configure the DHCP server on Subnet2 to provide the address 172.30.32.1 as the default gateway.
C.
On the Routing and Remote Access server, add a default route to 131.107.72.17.
D.
On the Routing and Remote Access server, add a default route to 172.30.32.1.
Explanation:
The routing and remote access server knows how to route traffic between subnet 1 and subnet 2. However, it doesn’t know how to route traffic to the internet. We can fix this by adding a default route on the routing and remote access server. The default route will tell the routing and remote access server that any traffic that isn’t destined for subnet1 or subnet2 (i.e. any external destination) should be forwarded to the internal interface of the ISA server (172.30.32.1).Reference:
